First hints at changing perceptions

Our on-going public opinion polling of beach goers in the wake of the Refugio Oil Spill is beginning to show some interesting patterns.  We are still in the midst of collecting data (check back in a week or two when we have had a chance to fully explore this data coming in daily), but a few trends are beginning to come into focus.

For example, there appears to be a difference in the public’s perception of the safety of seafood from the Santa Barbara area in the wake of the Refugio Spill.  As we have seen with the Deepwater Horizon in the Gulf of Mexico, the Fukushima disaster in Japan, and several other recent coastal catastrophes, the public is quick to take a dim view of the safety of food from impacted areas.  We have already seen a change in the perception of the safety of seafood from Santa Barbara relative to other regions of California (see figure below).

Our surveys ask if people feel seafood from various regions of the globe is safe to eat.  Below you will see our interim results as of this past Wednesday.  In the wake of the spill there is now an apparent hesitancy amongst a subset of the public with regards to consuming seafood from the spill-affected (and as always happens in such situations) and nearby regions.  This whole matter is complicated by the fact most people don’t ask about where their seafood comes from on a day-to-day basis, but that is a discussion for our post on seafood.

 

Is seafood from here safe to eat?

Other changes in levels of public sentiment are becoming evident.  This is perhaps best exemplified by changed support/opposition for offshore drilling off of our California coast.  As you may well expect, we have been finding decreased support in recent weeks for offshore oil and gas drilling in California waters relative to our “normal” opinions collected each fall (where we conduct 1,000 to 1,500 in person surveys each year from mid September to mid October).  The graph below contrasts our most recent fall data (2014) to data we have been collecting over the last few weeks.

We are also beginning to see the shaping up of possible geographic patterns of perceptions and behaviors related to the intensity of tar a region received over the past few weeks.  An example of this is our willingness to spend money based on where we are and how long we might stay around.  As of yet this is only hinted at in the patterns of responses we are seeing (i.e. it is not yet statically significant).  But as we increase our sample size, we may well see these differences become robust and statistically significant.  Unlike seafood, I would expect this effect to be comparatively fleeting.  Assuming this is a truly significant trend we are documenting, my best guess is that such a difference would have disappeared by the end of the summer tourist season (barring some unforeseen new development that would keep the spill in the public’s eye). The following figure hints that the more tarring a site accumulates, the lower the financial input to that beach and adjacent areas from beach-going visitors.  Presumably this is being driven by the fact that people are less likely to stay around.  I should note that these sites are not necessarily clumped in one or two spots adjacent to Refugio; the recent tarring across our region has afforded us a much more robust opportunity to study such questions without the typical spatial autocorrelation (that’s fancy statical talk for the problem that we sometimes have a situation where chance and happenstance corrupt our nice, objective exploration of the natural world and render powerless our normal tools to detect differences).  This data comes from more than 33 beaches/sampling points across our study region in coastal southern California.

How much money have you spent/will you spend at the beach this week?

My students, colleagues, and I are very keen to explore further the interactions across these coupled human-natural systems.  Many hypotheses and patterns are available for us to test given our wealth of long-term annual surveys and dozens of recent beach ecological assessments we have conducted over the previous weeks and years.  If only we didn’t need to sleep, we would have these analyses done by now!

Stay tuned.

Our ROVs: Prowling for Oil

Note: This is a partial re-post with some modifications from my students’ Aerial and Aquatic Robotic Research Blog.

Check out what my students are doing now and have been doing in recent months with these killer new tools here: The AARR PIRatE Lab Blog.  Several of them are exhibiting some of our flying and swimming units at the national DARPA Challenge finals all weekend in Pomona.  We were invited to participate in this event by the DoD both due to our excellent outreach and educational efforts across all education levels (middle school, high school, and university) and for our pioneering efforts to use cheap, open source robotics to monitor the coastal zone.  Combing the seafloor for oil is but our latest adventure and application for these powerful new tools for environmental assessment.  See my students’ blog for what we have been doing and consider swinging by the event at the Pomona Fairplex in Pomona, CA today for the free-to-the-public demos and competition.

What are we doing with robots?

We are using our cheap, small, open source robots to hunt for any evidence of deposited oil on the seafloor near the spill epicenter at Refugio State Beach on May 19.  We are interested in assessing the ocean floor near the oil spill site for the presence and density of any subsurface mats, tarballs, oiled algal stands/seagrass meadows, or signs of potentially affected wildlife.

Getting there has been half most of the challenge

We have been pursuing access to the seafloor in the restricted access zone (the area upcoast and downcast from the Refugio pipeline break) for the past two weeks (see Pacific Standard’s piece on this very issue here) through all the formal and informal channels we know of.  Daily calls and frequent electronic requests to the JIC and to incident command member agencies have gone nowhere and we still have not been granted access/permission to deploy our tools inside the immediate spill zone.  This has been frustrating as we believe we have unique tools that can document deposited oil on the benthos and create a visual record of the amount for the permanent/legal record.  Everyone we talk to seems to think our ROV (Remotely Operated Vehicle) survey is a great idea, but no one would pull the trigger to allow us or any of our partners access to the site.

As we have yet to secure legal permission to enter the area where oil was most likely deposited, we opted for the next best thing.  This past Thursday we did a quick inspection of Naples Reef, a Marine Protected Area about 14 km (8.5 mi) from the Refugio spill and an area outside the restricted zone.  Our Santa Barbara Channelkeeper colleagues have a keen and long-running interest in the goings on a Naples and have been anxious to confirm any (hopefully minor or non-existent) impacts to the reef.

Our motley crew (well, technically we in the PIRatE Lab’s AARR group are motley…our colleagues actual professionals) set out Thursday morning from the Santa Barbara Harbor aboard the Santa Barbara Channelkeeper’s converted 31-foot JC lobster boat the R/V Channelkeeper.

A fantastic team

One of the best things about creating and using new tools such as our ROVs is the associated chance to meet tons of great new colleagues and partners.  This initial hunt for benthic oil brought together three groups onboard the R/V Channelkeeper; our AARR team, Ben Pitterle from Santa Barbara Channelkeeper, and David Lang from OpenROV.  Ben helms all things watershed and marine-related for Channelkeeper as their Watershed and Marine Program Director.  David Lang is a co-founder of OpenROV and a partner on our current NOAA grant to educate K-12 students about our coastal environment via innovative curricula and tools (like ROVs).  See our recent OpenROV Explorer’s Google Hangout for more info (we talk about looking for oil starting around the 15 minute mark).

Any Oil?

So the buried lead here is that we detected no oil, although this initial survey was quite preliminary.  This is of course great news for Naples Reef and our nearshore environment!  It is also no surprise as any deposited oil would be most likely be concentrated and therefore observable in the immediate shallow subtidal near the pipeline break up at Refugio.  It is also important to note that with every passing day any deposited oil will likely become covered with sediment, detritus, etc. and be that much harder to detect with simple visual inspections.

A great test

This demo showed that our cheap ($1,000 baseline, $2,000 with our modifications) ROV can easily be used for subsurface surveys in the wake of oil spills.  Even on a day with poor visibility thanks to the previous nights drizzle.  Our small, OpenROV units are portable (fitting within a single Pelican Case or large backpack), adaptable (everything is open source and open to anyone to modify or adapt), and require minimal training (we can bring users up to speed in a handful of days).  These units are also easy to assemble (we are doing builds now for various non-robotics savvy labs).  Even we (our lab is pretty interdisciplinary but still dominated by ecologists, conservation biologists, and environmental scientists) can build these things…so you know they are user-friendly.

Lastly, it is key to reemphasize that these units could be considered expendable.  We are not a wealthy lab by any stretch of the imagination, but sending tech into the sea is always a challenge.  Sending tech into a natural disaster context on top of that already hostile milieu translates into a good chance you will lose or break something.  We believe it is much better to put a $2,000 unit that can be operated by undergraduates on the case and in harm’s way rather than a several hundred thousand dollar unit requiring highly specialized operators, support staff, etc.  This new tech we are proposing is both cheaper and much less riskier.   It is even opening the door to potential citizen science groups monitoring swaths of our coasts, oil spill or no.  How cool would that be?

 

This was a great proof of concept trial!  We now know that we can indeed use our versatile OpenROV platform to go hunt for oil.  We will be returning to sea next week to continue the hunt…hopefully with permission to enter the restricted zone.  Keep you fingers crossed!
